This blue Arcturus 145 tests 79/47 on my TV-7D tester (calibrated 1/27/24). Brand new tubes should test 72/47 or higher. Tested for shorts, emission, gas and noise.

This tube tests as strong as new! It is incredibly rare to find one in this condition that tests this well. It has an etched/engraved style base.

There is a scratched area on the underside of the base between the pins. See the pictures for condition and ask questions. This is strong, but I can’t prove it’s new so I consider it lightly used. I do not accept returns unless the item is not as described.

I’m in the process of listing thousands of tubes. If you want something in particular message me to see if I have it. Thanks!
